Be careful what you wish for. Bringing a test case to the current supreme court is playing with fire, and we are far more likely to end up with precedent rejecting a right to encrypted communications, given the current make up of the court. They have already shown a willingness to show deference to national security, and our fifth amendment protections are already eroding (State v. Andrews in NJ, government can compel the production of a password under the foregone conclusion exception). For now this is still state dependent, but its only a matter of time before a case reaches the supreme court.

We're much safer not opening that can of worms for now.
